Claims (5)

1. Способ управления резонансными частотами накладывающихся колебаний в ультразвуковых запечатывающих устройствах (1), в которых имеется расположенное в центре устройство возбуждения (2), окруженное телами реакции (3), и раструб (4) с вытянутой узкой поверхностью (5) запечатывания, отличающийся тем, что в телах реакции (3) имеются симметрично расположенные пазы (9), указанные пазы (9) располагаются там, где накладывающиеся колебания имеют максимум потенциала или наоборот максимальное смещение.1. A method for controlling the resonant frequencies of overlapping vibrations in ultrasonic sealing devices (1), in which there is a central excitation device (2) surrounded by reaction bodies (3) and a bell (4) with an elongated narrow sealing surface (5), characterized the fact that in the reaction bodies (3) there are symmetrically located grooves (9), these grooves (9) are located where overlapping vibrations have a maximum potential or vice versa a maximum displacement. 2. Способ по п. 1, отличающийся тем, что величина смещения частот зависит от высоты, глубины и длины паза (9). 2. The method according to p. 1, characterized in that the magnitude of the frequency offset depends on the height, depth and length of the groove (9). 3. Способ по п. 1, отличающийся тем, что управление резонансными частотами предполагает смещение накладывающихся колебаний, устойчивость которых уменьшается так, чтобы осуществить смещение. 3. The method according to p. 1, characterized in that the control of the resonant frequencies involves the displacement of overlapping oscillations, the stability of which decreases so as to effect an offset. 4. Способ по любому из пп. 1-3, отличающийся тем, что накладывающиеся резонансные частоты сдвигаются вниз в частотном диапазоне. 4. The method according to any one of paragraphs. 1-3, characterized in that the overlapping resonant frequencies are shifted down in the frequency range. 5. Способ по любому из пп. 1-3, отличающийся тем, что накладывающиеся резонансные частоты сдвигаются по меньшей мере на 1 кГц. 5. The method according to any one of paragraphs. 1-3, characterized in that the overlapping resonant frequencies are shifted by at least 1 kHz.
